My first time, a true story
My first time ever being hit in the balls by a girl happened some 13 years ago when I was just 19 years old. I was not aware of ballbusting as a fetish at the time but had always felt a bit vulnerable to girls because of my testicles and I'd seen girls kick other guys in the balls and how painful it looked, but I'd never been on the receiving end.
It was at a house party at a friend of mine, and I remember being a little conscious that a girl I really fancied was going to be there. Her name was Ellie and she was very much a girl next door type, brunette with little make up but just naturally stunning. At the same party was another girl called Stacey, who I was friends with and had a thing for me but I wasn't into her, not because she was unattractive but I just didn't see her that way.
During the night I saw Ellie chatting to a mutual friend of ours Justin but didn't think too much of it.
At about ten o'clock Ellie appeared and started coming towards me in the middle of the party. Before I knew what was happening she started kissing me, shoving her tongue in my mouth right in front of everyone who all started cheering. She moved my hands onto her ass which was in these really hot tight leggings, and I pretty much instantly got hard and had to readjust myself subtly so everyone didn't see.
It was here I felt her balance shift as she pulled out of the kiss and took a firm grip around my shoulders. With no warning I felt her knee slam into my nuts. In shock I fell to my knees but the pain hadn't fully kicked in yet. I looked up at Ellie standing over me, her camel toe only about an inch from my face and the pain started to really come together, my stomach tightening up and nuts throbbing. With a massive grin and with everyone laughing in the background she said "And that was only the left knee! Oh, and Justin just spunked in my mouth two minutes ago."
She turned to face everyone at the party, her ass so close to my face I could smell it and said "That's how you knee a guy in the balls!", and then slowly walked away leaving me crippled on the floor. Stacey came over to me to check I was OK and I could only say it hurts so bad. "Let's get those balls looked after" she said and helped me into one of the bedrooms to recover. I didn't realise at the time that was only the first time that night I would get busted.
